Steel manufacturing: From iron ore to finished product
Iron ore, coke and calcite (lime) are added to a blast furnace to produce molten iron. This iron is used as the raw material for steel manufacturing process. As you all might already know the basic process followed for making steel is by mixing carbon and iron at very high temperatures, above 2600°F. This method is of two types:

Wrought Iron Production
Pig iron has 3.5-4.5% carbon content and contains varying amounts of contaminants such as sulfur, silicon and phosphorus. Pig iron is not a salable product, but is an intermediate step in the production of wrought iron, steel and cast iron from iron ore. Wrought Iron was created from pig iron using innovative production systems during the ...

Identifying the Role of Limestone in Iron Manufacture
Haematite (text{Fe}_2text{O}_3text{)}, a naturally occurring form of iron ore, is reduced to iron in the blast furnace. This reduction process involves removing the oxygen from the ore, and this is typically done using carbon monoxide (text{CO}text{) as the reducing agent.

Applications of Iron Ore Pellets
This process of converting iron ore into pellets is known as Pelletization. Iron Ore Pellets are then used in the production of steel. Pellets are usually preferred instead of raw Iron Ore because it allows for maximum utilization of iron ore. This is important since iron ore reserves are depleting globally.
